About this study

Official title: Randomized, Double-Blinded Clinical Trial to Evaluate the Incidence and Severity of Neuropsychiatric Side Effects and Antiviral Efficacy of Efavirenz Given as a Stepped Dosage Over 2 Weeks Versus the Usual Dosage in HIV-Infected Patients.

Background: Neuropsychiatric side effects (NPSEs) occur in a significant proportion of subjects after initiation of efavirenz (EFV) and may limit its use in certain patients.

Objectives: To evaluate the incidence and severity of NPSEs and antiviral efficacy of EFV given as a stepped dosage over 2 weeks versus the usual dosage.

Methods: Randomized, double blind, multicentric clinical trial in which a progressive dosage (arm A: 200 mg qd for 6 days, 400 mg qd for 7 days and 600 mg qd from day 14 forward) was compared with conventional administration (arm B: 600 mg qd from the first day). All patients received additional treatment with 2 NRTIs.

The incidence and intensity of NPSEs and sleep disorders were assessed using a Likert-type scale specifically designed. Efficacy was assessed by percent of virological failures.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Efavirenz in people with HIV-1 Infection and HIV Infection, run by Sociedad Andaluza de Enfermedades Infecciosas at 10 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Jan 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

incidence and severity of neuropsychiatric side effects (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00556634, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2009.
